1. Product Introduction Summary

Our PICOGLF series off grid inverter is one of the largest DC to AC inverters in the world. The Global LF Series Pure Sine Wave Inverter is a combination of an inverter, trickle battery charger and an AC auto-transfer switch into one complete system, with a peak conversion efficiency of 94%. It is packed with unique features and it is one of the most advanced inverters on the market today. It features power factor correction, customizable AC and DC operation and a pure sine wave output with unprecedentedly high surge capability to meet demanding power needs of inductive loads without damaging the equipment. When utility AC power cuts off (or falls out of acceptable range), the transfer relay is de-energized, and the load is automatically transferred to Inverter mode. Once the qualified AC power is restored the relay is re-energized and the load is automatically reconnected to AC bypass mode. The priority is programmable.

Never install the inverter horizontally. Install the inverter so the LCD is easy to access and read. The inverter should have plenty of air flow all around the inverter for

proper cooling fan operation. Don't install the inverter where passersby or children can tamper or

access the unit.

5. Electrical Connection As mentioned several times in this manual, installation should be done by a licensed professional. The electrical connections should be tested immediately after the installation is completed.

Prechecks

All electrical connections must meet local electrical codes. Incorrect wiring and/or installation may damage the inverter and may cause bodily harm. Before making any connections or performing maintenance to the inverter, make sure all power is off and no voltage present on the AC and DC sides.

Test for correct grounding, using proper cable and fuse sizes. Use a fuse or breaker 12 inches off the battery bank. Confirm the front panel breakers are in the "OFF" position and confirm all connections are properly wired. Check that the DC input breakers are in the “OFF” position. The cable between the battery and inverter should be as short as possible to avoid voltage drop. Never turn off DC input breaker with the inverter on or under a load, damage to the breaker or the inverter will occur.

Ensure all air vents are free from obstructions and clear of dust and debris. Don’t connect ground wire (PE) of cabinet and neutral wire (N) together.

NOTE: Do not over shut DC breaker off during operation. To shut AC off, use AC breaker first, then disengage AC start switch. To shut down inverter completely, follow above steps first then turn off DC breaker. Shutting off DC breaker during operation and under a load will damage the breaker and cause arcing.

Warning！

Do not reverse the polarity when connecting to DC input terminals. Confirm your wires are connected properly. Use the proper size cable and use bigger cable to handle voltage drop for long distance runs. REVERSE POLARITY IS NOT COVERED UNDER WARRANTY.

Source ground to case ground must be isolated and wire length should be as short as possible. After all wire connections have been made, check all voltages to ensure the voltages are within inverter’s

specification. Never operate any inductive motor larger than 30% of the inverters output due to high startup surge. When turning on the DC input breakers, the breaker may trip or pop the first time. This is normal as

the large capacitors are rapidly charging. If this happens, simply reset the DC breakers. When powering on the inverter, we recommend turning on the output circuit breaker first, then turn

on start switch allowing a soft start of AC loads to avoid any damage by large inrush current to inverter.

Before performing checks or maintenance, open (off) AC breaker, turn off start switch, then open (off) DC breaker. Wait 5 minutes for energy to dissipate. Measure DC and AC voltages with a multimeter and ensure there is no voltage between DC side and AC side. The display will slowly dim and disappear as the voltage drops. Inverter may still be live and have voltage present in the off position due to the large capacitors. Never touch any connection prior to testing with a multimeter.

When the inverter is operating normally, it is typical to see a rise in temperature. The cooling fans will start when the temperature reaches @ 113°F.

Do not open inverter’s door or touch any wire while in operation.

NOTE

After all connections are made and voltages are verified with a multimeter, proceed to the startup procedure

in section 6.

When the inverter is running, it is normal for the inverter to get warm. To avoid injury, only touch the LCD display and start/stop switch. DO NOT TOUCH ANY BREAKERS WHILE INVERTER IS OPERATING. THIS M AY CAUSE BODILY HARM AND RUIN THE INVERTER.
